김수일,이홍석,노범섭 한국농화학회 1989 Applied Biological Chemistry (Appl Biol Chem) Vol.32 No.2

Bowman-Birk type protease inhibitors of soybeans were purified with gel filtration on Sephadex G-75. Significant differences were found in the content and in the electrophoretic patterns of the purified protease inhibitors. Ten among fourteen electrophoretic bands appeared as protease inhibitors. The chymotrypsin and trypsin inhibiting activities in soybeans showed three and four fold variation respectively. And the cultivars with higher chymotrypsin inhibiting activities seemed to have higher cysteine contents.

Retinoic acid가 배양중인 백서 구개 내측연상피세포에 미치는 영향

김수일,이영호,김원식 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.1

For the study on the effect of retinoic acid on the medial edge epithelial cells of fetal rat palate in vitro, the GD 15 fetal palatal shelves of Sprague-Dawley rats were cultured. Excised palatal shelves were placed on the milipore filter, and cultured in organ culture dish(Falcon 3037). Retinoic acid was dissolved in 0.1% DMSO and used at concentration of 10^-5M. The media were changed every 24hrs, and the palatal shelves were harvested after 24, 48, 72 hrs after culture. The palatal MEE cells were observed with LM & TEM. The results were as follows ; 1. The palatogenesis of rat in vitro was delayed more or less compared with in vivo. 2. In LM photographs, the palatogenesis was delayed in the retinoic acid-treated group significantly. 3. In TEM photographs, the number of hemidesmosomes and desmosomes were increased in the retinoic acid-treated group. The basal lamina in the retinoic acid-treated group was intact, but not in control group. Cytoplasmic condensations, nuclear fragmentations, and apoptotic bodies were found in the control group. According to the above results, it is considered that retinoic acid inhibits programmed cell death and enhances proliferation of cells of the medial edge epithelium of rat palate. However, the exact action mechanism of retinoic acid on programmed cell death of MEE cells are still unclear.

김수일,유지형,Kim, Soo Il,Yoo, Ji Hyeung 대한토목학회 1990 대한토목학회논문집 Vol.10 No.2

본 연구에서는 합리적이고 과학적인 포장 구조체의 유지 관리를 위하여 포장체의 구조적 상태를 평가하는데 중요하게 사용되는 포장체 각 층의 탄성계수 추정 방법에 대하여 연구하였다. 차량하중에 의한 포장체의 구조적 거동을 측정하는 비파괴시험 방법으로 Falling Weight Deflectometer(FWD)를 택하였으며, 측정 결과를 합리적으로 해석하기 위하여 다층탄성이론에 근거한 해석 프로그램을 사용하였다. 국내에서 널리 사용되고 있는 고속도로 단면 모델에 요인배치법(factorial design)을 적용하여 쇄석과 안정처리기층을 갖는 경우 각각에 대한 이론적 처짐특성을 분석하고, 이로부터 각 경우의 층별 탄성계수 추정식을 제안하였다. 처짐 변화율에 따른 탄성계수 변화율에 과한 상관식을 4층 구조체 층별로 개발함으로써 FWD시험의 처짐으로부터 포장체 각 층의 탄성계수를 추정할 수 있는 보다 효율적이며 정도가 높은 역산방법을 제안하고 이를 전산화하였다. 또한 4층 아스팔트 포장체의 실제 가능한 수치 모델에 대한 검증을 통하여 본 연구에서 제안한 역산 방법의 신뢰성 및 타당성을 입증하였다. An inverse self-iterative procedure is developed to determine layer moduli which are significant for the structural evaluation of pavements in developing rational and analytical rehabilitation technique. Falling weight deflectometer(FWD) is adopted as a non-destructive testing(NDT)device. The layer elastic theory is used to interpret NDT data. The theoretical deflection basins of pavement structures obtained by full factorial design are used for a parametric study on the characteristics of deflection basins and regression analyses. Regression equations to estimate layer moduli of flexible pavements are proposed through the regression analyses of theoretical deflection basins. The relationships between the rate of change of moduli and deflections are developed for the efficient iteration. An inverse self-iterative procedure to ensure the accuracy of the layer moduli is proposed. Validity and applicability of the developed procedure are verified through various numerical model tests.

김수일,조삼덕 연세대학교 대학원 1983 延世論叢 Vol.20 No.1

Geotextile effects as a reinforcement material are studied through the laboratory model tests of a strip footing on weak clays. In the experiments, the effects of the distance of footing from geotextile layer and footing embedment ratio are investigated. For the purpose of comparison, the experiments without geotextile are carried out for the same conditions as the experiments with geotextile. In all experiments, vertical drains utilizing non-woven fabrics are installed in the clay layer in square pattern to accelerate the consolidation. The experimental model has plane dimensions of 30cm×110cm. The height for the soil container is 70cm. The desired heights of sand is constructed over the 40cm deep clay layer. The time dependent pore pressured utilizing the 10 piezometers installed symmetrically on both sides of the wall at different heights. The time dependent deformations are measured utilizing the LED indicating lamp matrix inserted in sand layer, From the experiments, it is found that there is bearing capacity increse of 109 percent in case of settlement to footing width ratio of 1.0 while there is only 19 percent increase for the ratio of 0.05 when the ratio of sand layer depth to footing width is between 0.1~2.0 for the surface footing. The ratio of sand layer depth to footing width which gives the greatest geotextile effects falls between 0.5 and 1, 0. It is also found that there is bearing capacity increase of 118 percent in case of settlement to footing width ratio of 1.0 while there is only 11 percent increase for the ratio of 0.05 for the fouling embedment ratio between 0.5 and 2.0.

가상암반층의 깊이를 고려한 아스팔트 포장체의 층별 탄성계수 추정기법의 개발

김수일,이광호,Kim, Soo Il,Lee, Kwang Ho 대한토목학회 1993 대한토목학회논문집 Vol.13 No.4

본 연구에서는 비파괴 시험장비인 FWD를 사용하여 아스팔트 콘크리트 포장체 각 층의 탄성계수를 추정할 때 고려하여야 하는 가상암반층의 깊이를 FWD의 충격지속시간과 충격하중에 의한 포장체내의 압축과 속도로부터 산정할 수 있는 알고리즘을 제시하였다. 또한 FWD 시험자료를 입력치로하여 포장체 각 층의 탄성계수를 추정하는 전산 프로그램인 MFPD에 본연구에서 제시한 알고리즘을 적용 보완하였다. 보완된 MFPD의 탄성계수 추정결과에 대한 타당성을 살피기 위하여 FWD를 제작하여 현장시험을 실시하였으며 아울러 검증시험을 병행 실시하였다. 검증시험으로는 FWD 시험위치에서의 평판재하시험, 채취시료의 실내시험(마샬안정도시험, 압축시험), 표면파시험을 실시하였다. 이들 시험성과를 비교분석한 결과 가상암반층을 고려할 수 있도록 보완한 MFPD의 역산결과가 충분히 신뢰성 있음을 알 수 있었다. The computer program, MFPD, which is used to backcalculate the layer moduli of asphalt concrete pavement system is modified by contemplating the depth to virtual bedrock in this study. An algorithm to estimate the depth to virtual bedrock is developed through the analysis of FWD impulse load duration and the compression wave velocity of ground. For verification of the modified MFPD, FWD is fabricated and then FWD field tests and verification tests are carried out at the test sites. Plate loading tests and surface wave propagation tests are performed at FWD test sites. Laboratory tests (Marshall stability tests, unconfined compression tests) for sampled asphalt concrete specimens are also carried out. From comparison analysis, the validity and applicability of the modified MFPD are verified.

Cultural Component in the Content of Korean Studies and Language Education in Kazakhstan

김수일,라리오노바 한국글로벌문화학회 2018 글로벌문화연구 Vol.9 No.4

The study relevance both by the needs of methodical science in theoretical development of socio-cultural component in teaching a foreign language in general, and the needs of Kazakhstan higher education institutions for textbooks with a focus on "dialogue of cultures", providing for interconnected communicative and socio-cultural development of future professionals. The paper assesses the content of national-cultural component structure in teaching the Korean language to Kazakhstan University students. This study is determined both by the needs of methodical science in theoretical development of socio-cultural component of teaching a foreign language in general, and Kazakhstan higher education institutions’ needs for textbooks with a focus on "dialogue of cultures", providing for interconnected communicative and socio-cultural development of future professionals. The need to address the problem of the socio-cultural and national-cultural component in the content is caused by the new goal of teaching the Korean language, understood as developing students' ability of intercultural communication. The problem of creating an image of Korea, as a native Korean speaker’s country, as well as that of Kazakhstan, has a political sound, since its solution is connected with overcoming a possible barrier between the two peoples, the destruction of obstacles between Korean and Kazakhstan linguistic cultures. Intensification of an adult communicator’s social connections, expansion of his field of activity as a subject of the “cultural dialogue” makes the processes of communication increasingly diverse and intense. This requires improving the structure of a future Korean teacher’s thesaurus (model of consciousness) at all levels of his professional communicative activities.

김수일,Jerome R. Lechien,Tareck Ayad,Huan Jia,Seyyedeh Maryam Khoddami,Necati Enver,Sampath Kumar Raghunandhan,Abdul Latif Hamdan,은영규 대한이비인후과학회 2020 Clinical and Experimental Otorhinolaryngology Vol.13 No.3

Objectives. This study was conducted to investigate the current practices of Asian otolaryngologists for laryngopharyngeal reflux (LPR). Methods. An online survey about LPR was sent to 2,000 members of Asian otolaryngological societies, and a subgroup analysis was performed between Western and Eastern Asian otolaryngologists. The survey was conducted by the Laryngopharyngeal Reflux Study Group of Young Otolaryngologists of the International Federation of Oto-rhino-laryngological Societies. Results. Among approximately 1,600 Asian otolaryngologists, 146 completed the survey (62 from Western Asian countries, 84 from Eastern Asian countries). A substantial majority (73.3%) of the otolaryngologists considered LPR and gastroesophageal reflux disease to be different diseases. The symptoms thought to be closely related to LPR were coughing after lying down, throat clearing, and globus sensation. The findings thought to be closely related to LPR were posterior commissure granulations and hypertrophy, arytenoids, and laryngeal erythema. The respondents indicated that they mostly diagnosed LPR (70%) after an empirical therapeutic trial of proton pump inhibitors (PPIs). Although multichannel intraluminal impedance-pH (MII-pH) monitoring is a useful tool for diagnosing nonacid or mixed LPR, 78% of Asian otolaryngologists never or very rarely used MII-pH. Eastern Asian otolaryngologists more frequently used once-daily PPIs (64.3% vs. 45.2%, P=0.021), whereas Western Asian otolaryngologists preferred to use twice-daily PPIs (58.1% vs. 39.3%, P=0.025). The poor dietary habits of patients were considered to be the main reason for therapeutic failure by Asian otolaryngologists (53.8%). Only 48.6% of Asian otolaryngologists considered themselves to be adequately knowledgeable and skilled regarding LPR. Conclusion. Significant differences exist between Western and Eastern Asian otolaryngologists in the diagnosis and treatment of LPR. Future consensus statements are needed to establish diagnostic criteria and therapeutic regimens.

말레이시아 외교정책결정 요인 분석

김수일 국제지역학회 2001 국제지역연구 Vol.5 No.2

The purpose of this study underlines that what kind of aspects affect the determination of foreign policy in Malaysia. To examine this purpose, I have scrutinized three aspects, which are assumed to influence foreign policy, national interest, international system and the features of political system and personality of the leader. First of all, Malaysian foreign policy has been hinged on the concept of national interest. In fact, the main principle of foreign policy underlines the realization of each states vital interests so that the case of Malaysian is not exceptional. Second, the Malaysian foreign policy has also been affected by the change of international system such as the period of cold war, the period of detente and the period of post cold war. The reason why this affection has been possible is that Malaysia is not the super power state but only middle range state. Third, the Malaysian foreign policy has greatly been involved by the characters of political system and its leader. The case of the Raman government has been testified as one of the case studies for this purpose.
